Making charts in RaphaelJS that are 100% width?

Question

I have seen graphs in Flash & stuff that basically adapt nicely to whatever the size of the browser or flexible element they are inside of.... I'm not really too well versed with raphaelJS but can you do this, and if so, how?

Answer 1

In raphaeljs, you can call .setSize on a Raphael object to update its size. To adapt to runtime changes in browser window size, you can respond to a window resize event. Using jQuery, you could do:

// initialize Raphael object
var w = $(window).width(), 
    h = $(window).height();

var paper = Raphael($("#my_element").get(0), w,h);

$(window).resize(function(){
     w = $(window).width();
     h = $(window).height();
     paper.setSize(w,h);
     redraw_element(); // code to handle re-drawing, if necessary
});

Answer 2

This will get you a responsive SVG

var w = 500, h=500;
var paper = Raphael(w,h);
paper.setViewBox(0,0,w,h,true);
paper.setSize('100%', '100%');
